Re: STM32GENERIC, my arduino implementation

using my F407VE, tried with Serial1.print and SerialUART1.print etc no keyword hi-lighting with SerialUART1, does compile/run, no output on Serial1(UART1) FTDI usb block Serial1 is hi-lighted, but Serial1 not declared error message noticed yesterday, that the first error message is not necessarily t...

Re: Problem with measuring very short pulses

in the isr, test for the most common state first. i.e. assume the clock is already running i.e. timer_start not equal to zero.
initialising it to zero will occur only once.

Re: STM32GENERIC, my arduino implementation

These are connector details for STM32F407ZGT 'Devils Cross' black board: J6 / J7 / DS
Definitely generic as I2C and Flash pads are empty
The actual silk screen has some nice white dots and text on the underside for each, LED0 / LED1 / KEY1 / KEY2 etc

Hope of interest/use

Re: How long is the delay(1) actually.. CpuGetTicks()

how you compiling this ? uint32 is incorrect, try uint32_t. i've tried general 407v and black f407v, unfortunately i can't seem to find any output at all on ttyusb0 uart1, ttyusb1 uart2 dumped out a load of binary 0x00. i also had the st-link interface give errors, sometimes a reset was required exe...

Re: STM32F103C8T6-How to activate multiple UART Port

the peripherals can have their 'functional' pins moved. if you use something notionally on PB6, say I2C1-SCL; the alternate of the peripheral can be 'switched' to PB8; pull the datasheet and reference manual for the chip and the family respectively. search in each for 'alternate' it may help you to ...

Re: IDE with Eclipse with Jantje's plugin

the guard statements preventing multiple inclusion of the same file are slightly different, perhaps allowing the double inclusion of .h file symbols or the include file is a slightly different name, same result ?
possibly the config directories of the 'env in use' are clashing?

Re: dfu/upload not perfectly working

well part A fits the title perfectly i tend to use only a st-link egg for uploads on the jtag 20w while trying the various F407 versions (HAL/libmaple) i noticed that the restart doesn't always happen. then a reset always does, but not sure if an immediate recompile and download always does? btw bla...
